The document discusses different types of animals throughout the world. It covers vertebrate animals like mammals, birds, reptiles, amphibians and fish, as well as invertebrate animals like sponges, cnidarians, worms, molluscs, echinoderms and arthropods. For each group, it describes key characteristics like their nutrition, reproduction, physical features and habitats. The purpose is to educate about different animal classifications so students can choose one to research and describe its features.
3. IN GROUPS:
• You are going to choose an animal.
• Any animal will do it. Just think the animal
that you would like to choose and choose
it.
• It has to be a REAL animal. A dinosaur does
not count; we are talking about animals
that live nowadays.
• Once you have chosen your animal, you
are going to complete the chart given
about the features this animal presents.
• Think if the animal:
• Is vertebrate or invertebrate
• Is a herbivore, carnivore or omnivore
animal.
• Is a viviparous or an oviparous animal.
• Has special features: where does it live,
etcétera.
5. VERTEBRATES AND INVERTEBRATES
VERTEBRATE ANIMALS
• Vertebrate animals are those
animals that have a backbone and
a bony or cartilaginous skeleton.
Mammals, birds, reptiles,
amphibians and fish are vertebrate
animals.
INVERTEBRATE ANIMALS
• Invertebrate animals are those animals
that don’t have a backbone or spinal
chord. Most of the animals in the
world are invertebrates.. Sponges,
cnidarians, molluscs, arthropods,
worms and echinoderms are
invertebrate animals.
6. NUTRITION
HERBIVORES
• Herbivore animals are
those animals that only
feed on plants. Cows
are herbivore animals.
CARNIVORES
• Carnivore animals are
those animals that
only feed on other
animals and only eat
meat. Lions are
carnivore animals.
OMNIVORES
• Omnivore animals are
those animals that
can both feed on
animals or plants.
Humans or bears are
omnivore animals.
7. REPRODUCTION
VIVIPAROUS ANIMALS
• Viviparous animals develop their
babies inside the mother’s belly.
Mammals are viviparous animals.
OVIPAROUS ANIMALS
• Oviparous animals develop their babies
outside the mother’s belly. They develop
inside eggs. Birds, fish or amphibians are
oviparous animals.
8. YOUR ANIMAL’S
DESCRIPTION
Now, we are going
to describe our own
animal, the one that
we have chosen.
We will follow the
next path: features
(nutrition,
reproduction…) and
then, using the
information that
you found,
complete the
description.
10. MAMMALS
• Mammals are viviparous animals, with their skin covered with hair or fur, and
breathe the air through the lungs. There are four different groups:
• Carnivore mamals.
• Mammals with hooves: instead of toes, these mammals have hooves. Most of them
are herbivore, and some are omnivores.
• Primates: they have five fingers in each hand and five toes in each feet. Human
beings belong to this group.
• Cetaceans: they are aquatic mammals. Unlike fish, they have lungs, so they have to
take air through their blowhole once in a while to survive. Dolphins or whales are
cetaceans.
12. BIRDS
Birds are oviparous animals with the body covered with feathers. Most of them use
their wings to fly, and they have a beak to eat instead of a mouth. They breather
through their lungs. There are four different types of birds:
• Flightless birds: they cannot fly. Ostriches are flightless birds.
• Waterfowl: their feet are prepared to swim. Swans and ducks are waterfowl.
• Birds of prey: they are carnivores. They have strong claws and beaks. Eagles are birds
of prey.
• Songbirds: they are the largest group.
14. REPTILES• Reptiles are vertebrate, oviparous animals. Most of them are
terrestrial. They have their body covered in scales, and
breather air through their lungs. There are four different
groups:
• Lizards: terrestrial, carnivorous animals. They have short legs
and a tail. Some can remove the tail to confuse predators.
• Snakes: they have no legs, and slither on the ground.
• Crocodiles: they have their bodies covered with hard scales.
They are carnivore, and crocodiles and alligators belong to
this group.
• Tortoises and turtles: they have a hard Shell. Tortoises are
terrestrial, and turtles are aquatic.
16. AMPHIBIANS• Amphibians are both aquatic and terrestrial, and
oviparous animals. They have four legs, and their skin
is bare. They breathe through their lungs and skin.
• They Suffer metamorphosis. Metamorphosis is the
process of changing from a tadpole to an adult
amphibian.
AMPHIBIANS: terrestrial
and aquatic,
vertebrates, bare skin,
lungs and skin.
With a tail
Without a tail
17. FISH• Fish are aquatic, oviparous vertebrates. They
breathe through their gills, and their bodies are
covered with scales.
FISH: vertebrates,
aquatic, gills,
Bony fish Cartilaginous
fish
19. INVERTERBRATE ANIMALS
• There are lots of animals that are invertebrates. They
don’t have a backbone (also called spinal chord)
• There are six groups: sponges, cnidarians, worms,
molluscs, echinoderms and arthropods.
20. SPONGES
• They are very simple. They cannot move by themselves.
• Their sac-like bodies are covered of pores.
• They filter the nutritive substances in seawater for food.
21. CNIDARIANS
• They are aquatic invertebrates.
• They have got jelly-like bodies that look like UMBRELLAS.
• They have poisonous tentacles.
22. WORMS
• They have long, soft bodies.
• They haven’t got legs.
• Some live in the soil (like the earthworms) and other live in water (fireworms)
23. MOLLUSCS
• They have soft bodies, and protect themselves with one or two shells.
• They are oviparous.
• There are different groups:
• Bivalves
• Snails and slugs.
• Squids and cuttlefish.
• Octopuses:
25. ECHINODERMS
• They have a “skeleton” made of hard plates, often with spines.
• They are marine animals.
• There are two groups:
• Starfish
• Sea urchins
26. ARTHROPODS
• They are the largest group of animals.
• They have exoskeletons (like an armour)
• They have got legs and a segmented body.
• There are four groups:
• Insects
• Arachnids
• Crustaceans
• Myriapods
28. INSECTS
• They all have SIX LEGS and most of them TWO ANTENNAE.
• They can have either TWO or FOUR wings.
• The body is divided in three parts:
• The head: with the mouth, eyes and the antennae.
• The thorax: has got six legs and the wings.
• The abdomen.
They are oviparous and Suffer from Metamorphosis too.
29. OTHER ARTHROPODS
Arachnids
They have eight legs.
They haven’t got
antennae.
They produce silk to
create their webs.
Crustaceans
They have a hard
exoskeleton.
They have got antennae
and ten legs.
Myriapods
They have long bodies.
They have many
identical segments.
They have got a pair of
antennae.
